PuTTY makes explicit use of libX11 without including -lX11 on the
link line. (GNU ld appears to pull in libX11 automatically because
it's needed for the dependencies of GTK, but gold expects that
dependency to be satisfied at run time via DT_NEEDED and hence
doesn't bother.) Hence, add explicit -lX11 to both Makefile.gtk and
the autoconf world.

plink did not cope gracefully with this -- it was not possible to override that
hostname on the command line (attempts at doing so would be treated as part of
the remote command).
Fix this by applying the principle of r7265: if the user didn't explicitly
specify that they wanted to launch the hostname in the default (for instance
with '-load "Default Settings"', we assume they don't want to, and such a
hostname doesn't count when deciding whether to treat a non-option argument as
hostname or command.

and then let lpage_send() convert from UTF-8 back to whatever it's
supposed to actually go down the line in.

to a Unix-domain socket. This typically works fine when PuTTY is run on the
same machine as the X server, but it's broken multi-hop X forwarding through
OpenSSH; when OpenSSH creates a proxy X server "localhost:10", it only listens
on TCP, not on a Unix-domain socket.
Instead, when deciding on the details of the display, we actively probe to see
if there's a Unix-domain socket we can use instead, and only use it if it's
there, falling back to the specified IP "localhost" if not.
Independently, when looking for local auth details in Xauthority for a
"localhost" TCP display, we prefer a matching Unix-domain entry, but will fall
back to an IP "localhost" entry (which would be unusual, but we don't trust a
Windows X server not to do it) -- this is a generalisation of the special case
added in r2538 (but removed in r8305, as the automatic upgrade masked the need
for it).
(This is now done in platform-independent code, so a side-effect is that
get_hostname() is now part of the networking abstraction on all platforms.)

that we can now support X authority lookups on Windows as well

arbitrary choice of the first returned address in functions like
sk_getaddr and sk_address_is_local - what if, for instance, a DNS

Jacob points out, however, that his system not only has a namespace
clash but worse still the clash is at the name "fixed", which is our
default font! So, modify my namespace policy to use the
disambiguating prefixes everywhere by default, and use _unprefixed_
names only if the user types one in by hand.
In particular, I've changed the keys used to store font names in
Unix saved session files. Font names read from the new keys will be
passed straight to the new unifont framework; font names read from
the old keys will have "server:" prepended. So any existing
configuration file for GTK1 PuTTY should now work reliably in GTK2

explicitly deals with GdkFont out into a new module, behind a
polymorphic interface (done by ad-hoc explicit vtable management in
C). This should allow me to drop in a Pango font handling module in
parallel with the existing one, meaning that GTK2 PuTTY will be able
to seamlessly switch between X11 server-side fonts and Pango client-
side ones as the user chooses, or even use a mixture of the two
(e.g. an X11 font for narrow characters and a Pango one for wide
characters, or vice versa).
In the process, incidentally, I got to the bottom of the `weird bug'
mentioned in the old do_text_internal(). It's not a bug in
gdk_draw_text_wc() as I had thought: it's simply that GdkWChar is a
32-bit type rather than a 16-bit one, so no wonder you have to
specify twice the length to find all the characters in the string!
However, there _is_ a bug in GTK2's gdk_draw_text_wc(), which causes
it to strip off everything above the low byte of each GdkWChar,
sigh. Solution to both problems is to use an array of the underlying
Xlib type XChar2b instead, and pass it to gdk_draw_text() cast to
gchar *. Grotty, but it works. (And it'll become significantly less
grotty if and when we have to stop using the GDK font handling
wrappers in favour of going direct to Xlib.)

- New dlg_label_change() function in the dialog.h interface, which
alters the label on a control. Only used, at present, to switch
the Host Name and Port boxes into Serial Line and Speed, which
means that any platform not implementing serial connections (i.e.
currently all but Windows) does not need to actually do anything
in this function. Yet.
- New small piece of infrastructure: cfg_launchable() determines
whether a Config structure describes a session ready to be
launched. This was previously determined by seeing if it had a
non-empty host name, but it has to check the serial line as well
so there's a centralised function for it. I haven't gone through
all front ends and arranged for this function to be used
everywhere it needs to be; so far I've only checked Windows.

more useful. Unfortunately, PuTTY's NetHack keypad mode doesn't
support Ctrl-moves. Therefore, it does now :-)

basis for other terminal-involving applications: a stub
implementation of the printing interface, an additional function in
notiming.c, and also I've renamed the front-end function beep() to
do_beep() so as not to clash with beep() in lib[n]curses.

abstracted out; replace loops structured around a single interaction
per loop with less tortuous code (fixes: `ki-multiprompt-crash',
`ssh1-bad-passphrase-crash'; makes `ssh2-password-expiry' and
`proxy-password-prompt' easier).
The new interaction abstraction has a lot of fields that are unused in
the current code (things like window captions); this is groundwork for
`gui-auth'. However, ssh.c still writes directly to stderr; that may
want to be fixed.
In the GUI apps, user interaction is moved to terminal.c. This should
make it easier to fix things like UTF-8 username entry, although I
haven't attempted to do so. Also, control character filtering can be
tailored to be appropriate for individual front-ends; so far I don't
promise anything other than not having made it any worse.
I've tried to test this fairly exhaustively (although Mac stuff is
untested, as usual). It all seems to basically work, but I bet there
are new bugs. (One I know about is that you can no longer make the
PuTTY window go away with a ^D at the password prompt; this should be
fixed.)

Use the POSIX PATH_MAX if it exists, and fall back to 1024 otherwise.
We should really allocate filenames dynamically if PATH_MAX isn't defined.

Unix Plink sends everything sensible it can find, and it's fully configurable

I'm not entirely sure about the precise set of modes that Unix Plink should
look at; informed tweaks are welcome.

that the global `sesslist' got out of sync with the saved-sessions submenu,
causing the latter to launch the wrong sessions.
Also, Change Settings wasn't getting a fresh session list, so if the set of
sessions had changed since session startup it wouldn't reflect that (at least
until a session was saved). Fixed (on all platforms).
Therefore, since the global sesslist didn't seem to be useful, I've got rid
of it; config.c creates one as needed, as do the frontends. (Not tried
compiling Mac changes.)
Also, we now build the saved-sessions submenu on demand on Windows and Unix.
(This should probably also be done on the Mac.)

in question vary per OS: on Windows the problem is that WM_TIMER
sometimes goes off too early, so that GetTickCount() is right and
the callback time is wrong, whereas on Unix the problem is that my
GETTICKCOUNT implementation comes from the system clock which means
it can change suddenly and non-monotonically if the sysadmin is
messing about (meaning that the timing of callbacks from GTK or
select timeouts is _more_ likely to be right than GETTICKCOUNT).
This checkin provides band-aid workarounds for both problems, which
aren't pretty but ought to at least prevent catastrophic assertion
failure.

glibc-2.3.3-118 and Debian libc6 2.3.2.ds1-20) have clock_gettime() and

* All the PuTTY tools for Windows and Unix now contain the fingerprints of
the Master Keys. The method for accessing them is crude but universal:
a new "-pgpfp" command-line option. (Except Unix PuTTYgen, which takes
"--pgpfp" just to be awkward.)
* Move the key policy discussion from putty-website/keys.html to
putty/doc/pgpkeys.but, and autogenerate the former from the latter.
Also tweak the text somewhat and include the fingerprints of the
Master Keys themselves.
(I've merged the existing autogeneration scripts into a single new
one; I've left the old scripts and keys.html around until such time
as the webmonster reviews the changes and plumbs in the new script;
he should remove the old files then.)

connection_fatal(), since the latter is entitled to destroy the

For the Unix port, switch exit(0) to gtk_main_quit() in

This was harder than verify_ssh_host_key() and askalg() put
together, because:
(a) askappend() can be called at any time, since it's a side effect
of data-logging functions. Therefore there can be an unfinished
askappend() alert at any time, and hence the OS X front end has
to be prepared to _queue_ other alerts which occur during that
time.
(b) logging.c has to do something with data that comes in while
it's waiting for an answer to askappend(). It buffers it until
it knows what the user wants done with it. This involved
something of a reorganisation of logging.c.
[originally from svn r5344]
now returns an integer: 0 means cancel the SSH connection and 1
means continue with it. Additionally, they can return -1, which
means `front end has set an asynchronous alert box in motion, please
wait to be called back with the result', and each one is passed a
callback function pointer and context for this purpose.
I have not yet done the same to askappend() yet, because it will
take a certain amount of reorganisation of logging.c.
Importantly, this checkin means the host key dialog box now works on
OS X.

structure, in preparation for wanting more than one of them in a
single process. This can't be done cleanly, because the whole
business with pty_pre_init pre-allocating the pty rather assumes we
want a known number of the things before we drop privileges; so
there's a horrid hack to make pty_pre_init work on platforms that
have at most one pty instance per process, but at the same time
things ought to work sensibly with more than one per process _if_
pty_pre_init isn't required.

/dev/ptyXX we can open: we must also check that we can open and use
the corresponding /dev/ttyXX, because if it's been left in the wrong

discover our pty is unusable.

* Make sk_getxdmdata() return an arbitrary string rather than two integers.
This better matches the spec, even if the current version always returns
six bytes
* On Unix, for PF_UNIX sockets, return a counter rather than a constant along
with the PID. This should allow multiple clients to connect within one
second, and is what Xlib does.
* On Unix, interpret AF_INET6 addresses like Xlib does, returning the
embedded IPv4 address for v4-mapped addresses, and six bytes of zeroes
otherwise. The latter is silly, but if I'm going to do anything more sane
I need to check that X servers won't reject it.

of polishing to bring them to what I think should in principle be
release quality. Unlike the unfix.org patches themselves, this
checkin enables IPv6 by default; if you want to leave it out, you
have to build with COMPAT=-DNO_IPV6.
I have tested that this compiles on Visual C 7 (so the nightlies
_should_ acquire IPv6 support without missing a beat), but since I
don't have IPv6 set up myself I haven't actually tested that it
_works_. It still seems to make correct IPv4 connections, but that's
all I've been able to verify for myself. Further testing is needed.
